I was thinking about that yesterday too. However the direction my brain jumped from the "what if skittles is actually behind it all" to about what Datu said he was kind of "sitting back away from what he could see, like he was in the back seat if his mind."

What if that is what happens. They are still there but have no control. They are forced to watch all the horrible things their body is doing. While someone else controls it. And if that is the case a ton of possibilities open. Such as

-you can't be controlled effectively all the time (Datu resisting)
-Inks experiments are attempts to strengthen a person against resistance to the control.
-capturing Saul was a move to get Tanya (failed attempt at tower)

Of course a different big "oh crap" would be if the infection started with an animal at the emergency clinic Tanya worked at. And ink was given a sample to analyze and the family he killed were the pet's owners.
